Past, Present, Future
ITER is expected to achieve first plasma within this year
What is 2033/2034?
In cases where the plasma density in tokamaks is not monotonic, this diagnostic may be applied in favor of reflectometry.
What is Thomson Scattering?
The time that peak fusion rate occurs during the implosion of a deuterium pellet.
What is the moment of contraction?
This technique to produce electron density profiles from reflectometry is limited by amount of chordal measurements.
What is Abel Inversion?
The distance at which an individual electric charge is screened by bulk plasma.
What is Debye Length?
This facility famously shutdown during Reagan Era due to budget cuts
What is the Mirror Fusion Test Facility (MFTF)
When a magnetic field is applied to a plasma, the trace of a langmuir probe changes in this way.
What is decreased ion saturation current?
In Z-Pinch devices, the mitigation of these two modes is critical to its performance.
What is the sausage and kink mode?
This relaxation causes massive temperature and density drop in the core of tokamak plasma.
What is a sawtooth crash?
This equation defines the plasma beta quantity:
What is:...
This divertor tokamak hailing from Germany first began operation in 1991. It has since appeared in many papers we have reviewed.
What is the ASDEX Upgrade?
A knife edge is used during Schlieren spectroscopy for this reason.
What is decreasing intensity of the final image in order to discern the diffraction pattern?
This theoretical fusion technique believed to be a cheap and efficient source of energy has yet to demonstrate actual fusion
What is cold fusion?
What is Neutral Beam Injection, ECRH/ICRH, RF Heating
These three ways are the main descriptions of plasma dynamics.
Single Particle Motion, MHD/Fluid Picture and Kinetic Theory/Scale
This current fusion device holds the record for the most power produced during a single experiment
What is JET? Joint European Torus
This phenomenon allows temperature fluctuation measurements in tokamaks through the use of grating polychromators or heterodyne receivers.
What is cyclotron emission?
In the DIII-D tokamak, this method decreased turbulent fluctuations by 10-15%.
A paper published in 2024 presented results where this empirical electron density threshold was exceeded.
What is the Greenwald Limit?
This instability arises in magnetized plasma when parallel pressure exceeds perpendicular pressure.
What is firehose instability?
In 1968 this Soviet fusion device achieved plasma temperature of ~10 million degrees with good confinement.
The T-3 Tokamak
What is a Rogowski coil?
It is in the direction of this motion in which neutral beams are injected in Norman/C-2W (at TAE Technologies) to drive the Field Reversed Configuration (FRC).
What is the ion diamagnetic drift?
This condition helped increase the period of sawtooth crashes in the HBT-EP tokamak.
Hint: When this parameter is manipulated, the safety factor decreases.
What is decreasing the wall radius?
In ideal MHD, this dimensionless quantity must be much greater than 1 to satisfy the 'frozen-in' condition.
What is Magnetic Reynolds/Lundquist number?
